Consumer medicine information (CMI) leaflet

Please read this leaflet carefully before you start using Movapo and Movapo PFS.

What is in this leaflet

This leaflet answers some common questions about MOVAPO and MOVAPO Pre-Filled Syringe (PFS). It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you using MOVAPO or MOVAPO PFS against the benefits they expect it will have for you.

If you have any concerns about using this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

For further information on MOVAPO or MOVAPO PFS please refer to “A guide to the use of apomorphine in the treatment of Parkinson’s Disease for patients and carers” which is available from STADA Pharmaceuticals Australia Pty Ltd.

What MOVAPO and MOVAPO PFS are used for

MOVAPO and MOVAPO PFS contain apomorphine which belongs to a group of medicines called dopaminergic compounds.

Apomorphine is used in the treatment of Parkinson’s disease to reduce the number and severity of bouts of freezing and stiffness (or “off” periods).

This medicine works by acting on dopamine receptors. These receptors help control movement by the body.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

This medicine is not addictive. This medicine is available only with a doctor’s prescription.

Before you use MOVAPO or MOVAPO PFS

When you must not use it

Do not use MOVAPO Injection or MOVAPO PFS if you have an allergy to:

  • any medicine containing apomorphine or sodium metabisulfite
  • any of the ingredients listed at the end of this leaflet
  • certain types of pain killers such as morphine or other opioid analgesics.

Some of the symptoms of an allergic reaction may include:

  • shortness of breath
  • wheezing or difficulty breathing
  • swelling of the face, lips, tongue or other parts of the body
  • rash, itching or hives on the skin.

Do not use this medicine if you have or have had any of the following medical conditions:

  • certain forms of dementia e.g. Alzheimer’s Disease
  • severe kidney or liver disease
  • problems with circulation of blood in the brain (cerebrovascular disease)
  • breathing problems (respiratory depression).

Do not give this medicine to a child under the age of 18 years.

Do not use this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering. If it has expired or is damaged, return it to your pharmacist for disposal.

If you are not sure whether you should start using this medicine, talk to your doctor.

Before you use it

Tell your doctor or pharmacist if you have allergies to any other medicines, foods, preservatives or dyes.

Tell your doctor if you have or have had any of the following medical conditions:

  • a history of severe nausea and vomiting
  • heart disease
  • kidney disease
  • liver disease
  • lung disease
  • problem gambling
  • any addictive behaviour (e.g. sex, shopping or eating)

Before you use MOVAPO PEN, your doctor will obtain an ECG (electrocardiogram) and will ask for a list of all other medicines you take. This ECG will be repeated in the first days of your treatment and at any point if your doctor thinks this is needed. He or she will also ask you about other diseases you may have, in particular concerning your heart. Some of the questions and investigations may be repeated at each medical visit. If you experience symptoms which may come from the heart, e.g. palpitations, fainting, or near-fainting, you should report this to your doctor immediately. Also, if you experience diarrhoea or start a new medication, this should be reported to your doctor.

Tell your doctor if you are pregnant or plan to become pregnant or are breastfeeding. Your doctor will discuss with you the possible risks and benefits involved.

If you have not told your doctor or pharmacist about any of the above, tell them before you start using MOVAPO or MOVAPO PFS.

Taking other medicines

Tell your doctor or pharmacist if you are taking or using any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.

Some medicines, MOVAPO Injection and MOVAPO PFS may interfere with each other. These include:

  • tetrabenazine, a medicine used to treat movement disorders
  • metoclopramide, a medicine used to treat nausea
  • medicines used to treat some psychiatric (mental) conditions (e.g. phenothiazines, haloperidol, flupenthixol)
  • papaverine, a medicine which expands blood vessels
  • amphetamines

These medicines may be affected by MOVAPO and MOVAPO PFS, or may affect how well they work. You may need different amounts of your medicines, or you may need to use different medicines.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while using this medicine.

How to use MOVAPO and MOVAPO PFS

Follow all directions given to you by your doctor, nurse or pharmacist carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions, ask your doctor, nurse or pharmacist for help.

Do not use MOVAPO or MOVAPO PFS if the solution has turned green or if the solution is cloudy or you can see particles in it.

How much to use

Your doctor will decide what dose you will receive. This depends on your initial response to MOVAPO.

How to use it

You will usually be in hospital when you start using MOVAPO. It is recommended that you are given an anti-nausea drug (domperidone) and that you stop all your other anti-Parkinsonian medication before you start using MOVAPO. This medicine is given as an injection under the skin (subcutaneously), usually into your lower abdomen or outer thigh. It is either injected several times a day or continuously as an infusion (i.e. slow injection via a pump).

MOVAPO PFS is a pre-diluted, pre-filled syringe intended for use as a continuous infusion with a suitable pump/syringe driver. There is no need to dilute MOVAPO PFS prior to use.

When using MOVAPO ampoules to prepare a continuous infusion, it is recommended that MOVAPO is first diluted with an equal volume of sodium chloride 0.9% (normal saline). When using MOVAPO ampoules for intermittent injections, it is not necessary to dilute the MOVAPO.

It is advisable to change the site of injection every time you insert the needle to avoid getting lumps under the skin,

The medicine is for individual patient use only.

You and/or your carers will be trained by hospital staff to recognise when and how to give the injections.

If you use too much (overdose)

Immediately notify your doctor or nurse, or if you are not in hospital, telephone the Poisons Information Centre (telephone 13 11 26 in Australia or 0800 POISON or 0800 764 766 in New Zealand) or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have used too much MOVAPO or MOVAPO PFS. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Symptoms of an overdose may include severe nausea and vomiting, slow or troubled breathing, restlessness, hallucinations or unconsciousness.

While you are using MOVAPO and MOVAPO PFS

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are using MOVAPO or MOVAPO PFS.

Tell any other doctors, dentists and pharmacists who are treating you that you are using this medicine.

If you plan to have surgery, tell the surgeon or anaesthetist that you are using this medicine. It may affect other medicines used during surgery.

If you become pregnant while you are using this medicine, tell your doctor immediately.

Keep all of your doctor's appointments so that your progress can be checked.

Things you must not do

Do not use MOVAPO or MOVAPO PFS to treat any other complaints unless your doctor tells you to.

Do not give this medicine to anyone else, even if they have the same condition as you.

Things to be careful of

Be careful driving or operating machinery until you know how MOVAPO or MOVAPO PFS affects you. This medicine may cause drowsiness, sudden onset of sleepiness, dizziness or light- headedness in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.

3 Pharmaceutical Form

Solution for injection in prefilled syringe.
Movapo Pre-Filled Syringe (PFS) is a clear solution, practically colourless, odourless and practically free from visible particles.

4 Clinical Particulars

4.1 Therapeutic Indications

Movapo PFS is indicated to reduce the number and severity of 'off' phases in patients with Parkinson's disease severely disabled by motor fluctuations refractory to conventional therapy. Initiation of therapy with apomorphine should be undertaken in a specialist unit in a hospital setting. Conventional therapy should be continued during 'on' phases.

4.2 Dose and Method of Administration

The optimal dosage of Movapo PFS has to be determined on an individual patient basis. Hospital admission under appropriate specialist supervision is advised when establishing a patient's therapeutic regime.
It is essential that the patient is established on the antiemetic domperidone for at least 48-72 hours prior to initiation of therapy.
Movapo PFS is a pre-diluted prefilled syringe intended for use as a continuous subcutaneous infusion with suitable pumps/syringe drivers.
There is no need to dilute Movapo PFS prior to use.
Movapo PFS is for single use in one patient only. Contains no antimicrobial agent. For microbial reasons, once opened the contents of the prefilled syringe should be used for infusion immediately. The infusion site should be changed every 12 hours. Any unused solution should be discarded.
Do not use if the solution has turned green. The solution should be inspected visually prior to use. Only clear, colourless and particle free solution should be used.
Movapo PFS must not be used via the intravenous route.

Patient selection.

For patients in whom conventional therapy has failed, Movapo PFS is only considered to be suitable for Parkinson's disease patients capable of recognising and anticipating 'off' phases in motor performance. Movapo PFS is contraindicated in children and adolescents up to 18 years of age (see Section 4.3 Contraindications).
The elderly are well represented in the population of patients with Parkinson's disease and constitute a high proportion of those studied in clinical trials of apomorphine. The management of elderly patients treated with apomorphine has not differed from that of younger patients, except for the extra caution on commencing therapy, because of the risk of postural hypotension.
Patients who have shown a good 'on' period response during the initiation stage of apomorphine therapy, but whose overall control remains unsatisfactory using intermittent injections, or who require many and frequent injections, may be commenced on or transferred to continuous subcutaneous infusion by minipump and/or syringe driver.
The practical steps described below should be followed when commencing a patient on treatment:
Pre-treat with domperidone.
Discontinue all existing antiparkinsonian medication to provoke an 'off' phase in motor performance.
Determine the threshold dose response to Movapo injection (10 mg/mL) that produces an unequivocal motor response.
Re-establish other antiparkinsonian agents.
Determine effective treatment regimen for Movapo, initially intermittent SC, then infusion as necessary.
Teach patient and/or carer how and when to administer.
Discharge from clinic or hospital.
Monitor frequently and adjust dosage regimen as appropriate.
Full details are given below.

Pre-treatment.

Domperidone is a peripherally acting dopamine receptor antagonist given by mouth to prevent nausea and vomiting. Domperidone is commenced 48-72 hours prior to the first dose of Movapo injection (10 mg/mL). When patients are stabilised with respect to dosage of Movapo injection (10 mg/mL), the dose of domperidone is reduced by 10 mg per day every week until mild nausea appears. The maintenance dose of domperidone is the lowest level which completely prevents nausea. Domperidone can usually be withdrawn after several weeks. Before the decision to initiate domperidone and apomorphine treatment, risk factors for QT interval prolongation in the individual patient should be carefully assessed to ensure that the benefit outweighs the risk (see Section 4.4 Special Warnings and Precautions for Use). The cardiovascular assessment should include an ECG and QT measurement. Patients with severe renal insufficiency will require the dosing interval of domperidone to be changed from three times a day to once or twice a day. For further information regarding domperidone refer to the product information.

After provoking an 'off' phase in motor performance.

Determination of the threshold dose.

Movapo injection (10 mg/mL) is recommended.

Initiation of treatment.

Following establishment of an acceptable threshold dose of Movapo injection (10 mg/mL), the patient should be restarted on conventional antiparkinsonian therapy.
Once this is optimised, it is then usual to commence intermittent SC injection using the Movapo injection 10 mg/mL preparation.
See Section 4.2 Dose and Method of Administration, Patient selection for information on patients who may be suitable for treatment by continuous SC infusion.
Continuous subcutaneous infusion of Movapo PFS is administered by portable syringe driver. The dose should be titrated to the patient's response. Infusion rates can be commenced at 1 mg/hr, and then increased as necessary. The maximum daily dose should in general not exceed 200 mg/day. In clinical studies the required infusion rate varies between 1.25 and 5.5 mg/hr (equivalent to 0.02 and 0.08 mg/kg/hr), with most patients requiring (a total of) between 2 and 4 mg/hr.
Infusions should be run for waking hours only. Unless the patient is experiencing night time problems, 24 hour infusions are not advised. Tolerance does not seem to occur unless the overnight period without treatment is less than 4 hours. The infusion site should be changed every 12 hours. Prolonged infusion times are associated with local adverse effects to a more severe degree.
Patients may need to supplement their continuous infusion with intermittent bolus boosts, as necessary, and as directed by their physician.
A reduction in dosage of other dopamine agonists may be considered during continuous infusion.

Monitoring treatment.

Long term specialist supervision of patients is advised.
There is a high probability of adverse effects to Movapo PFS therapy. The frequency and severity of adverse events should be monitored carefully at regular intervals and a reassessment of the patient carried out if appropriate. Adjustments to the dosage or discontinuation may be necessary.

4.3 Contraindications

Movapo PFS is contraindicated in patients with a known hypersensitivity or allergy to apomorphine, morphine or chemically related products.
Movapo PFS should not be administered to patients with pre-existing neuropsychiatric problems or dementias due to either pathological processes, e.g. Alzheimer's disease, or to patients whose 'on' response to L-dopa is marred by severe dyskinesia, hypotonia or psychotoxicity.
Movapo PFS is also contraindicated in patients with inadequate renal or liver function, unstable coronary vascular disease, cerebrovascular disease, respiratory depression or CNS depression.
Movapo PFS is contraindicated for children and adolescents under 18 years of age.
Movapo PFS is contraindicated in patients with a known hypersensitivity to sodium metabisulfite.
Concomitant use with 5HT3 antagonists including antiemetics (for example ondansetron, granisetron, palonosetron) is contraindicated (see Section 4.5 Interactions with Other Medicines and Other Forms of Interactions).

4.4 Special Warnings and Precautions for Use

For subcutaneous use only (see Section 4.8 Adverse Effects (Undesirable Effects)).
Patients sensitive to morphine or its derivatives may be sensitive to Movapo PFS. Movapo PFS should therefore not be administered to patients with a known hypersensitivity or allergy to apomorphine, morphine or chemically related compounds (see Section 4.3 Contraindications).
Movapo PFS contains sodium metabisulfite which may cause allergic type reactions, including anaphylactic symptoms and life threatening or less severe asthmatic episodes in susceptible people (see Section 4.3 Contraindications).
In patients with cardiac decompensation or cerebrovascular disease, vomiting may cause an increase in blood pressure that may lead to haemorrhage and vascular accidents. Apomorphine is therefore contraindicated in these patients (see Section 4.3 Contraindications).
Caution should be used in administering Movapo PFS to patients with a predisposition to nausea and vomiting. Apomorphine may cause an increased risk of persistent vomiting. A risk-benefit assessment should be considered in these patients.
Since apomorphine may produce hypotension, even when given with domperidone pre-treatment, care should be exercised in patients with pre-existing cardiac disease or in patients taking vasoactive medicinal products such as anti-hypertensives, and especially in patients with pre-existing postural hypotension.
Since apomorphine, especially at high doses, may have the potential for QT prolongation, caution should be exercised when treating patients at risk for torsades de pointes arrhythmia.
When used in combination with domperidone, risk factors in the individual patient should be carefully assessed. This should be done before treatment initiation, and during treatment. Important risk factors include serious underlying heart conditions such as congestive cardiac failure, severe hepatic impairment or significant electrolyte disturbance. Also medication possibly affecting electrolyte balance, CYP3A4 metabolism or QT interval should be assessed.
Monitoring for an effect on the QTc interval is advisable. An ECG should be performed:
prior to treatment with domperidone;
during the treatment initiation phase;
as clinically indicated thereafter.
The patient should be instructed to report possible cardiac symptoms including palpitations, syncope, or near-syncope. They should also report clinical changes that could lead to hypokalaemia, such as gastroenteritis or the initiation of diuretic therapy. At each medical visit, risk factors should be revisited.
Apomorphine is associated with local subcutaneous effects. These can sometimes be reduced by the rotation of injection sites or possibly by the use of ultrasound (if available) in order to avoid areas of nodularity and induration (see Section 4.8 Adverse Effects (Undesirable Effects)).
Haemolytic anaemia and thrombocytopenia have been reported in patients treated with apomorphine. Haematology tests should be undertaken at regular intervals as with levodopa, when given concomitantly with apomorphine.
Caution is advised when combining apomorphine with other medicinal products, especially those with a narrow therapeutic range (see Section 4.5 Interactions with Other Medicines and Other Forms of Interactions).
Neuropsychiatric problems co-exist in many patients with advanced Parkinson's disease. There is evidence that for some patients neuropsychiatric disturbances may be exacerbated by apomorphine. Special care should be exercised when apomorphine is used in these patients. Apomorphine has been associated with somnolence and episodes of sudden sleep onset, particularly in patients with Parkinson's disease. Patients must be informed of this and advised to exercise caution while driving or operating machines during treatment with apomorphine. Patients who have experienced somnolence and/or an episode of sudden sleep onset must refrain from driving or operating machines. Furthermore a reduction of dosage or termination of therapy may be considered.
The use of apomorphine in conjunction with levodopa treatment may cause Coombs' positive haemolytic anaemia. An initial screen prior to commencement of treatment and at 6 monthly intervals is recommended. In the event of the development of a haemolytic anaemia, a haematological specialist should be consulted. The dose of apomorphine and/or levodopa should be reduced, with careful monitoring of the patient's motor state. It may be necessary to discontinue treatment with levodopa and/or apomorphine in the event that it is not possible to control the anaemia satisfactorily.
Apomorphine should be used with caution in patients with endocrine, renal, pulmonary or cardiovascular disease.
Periodic evaluation of hepatic, haemopoietic, renal and cardiovascular function is advised.
Patients with severe renal insufficiency may require the dosing interval for domperidone to be less frequent (see Section 4.2 Dose and Method of Administration, Pre-treatment).

Neuroleptic malignant syndrome.

Symptoms suggestive of neuroleptic malignant syndrome (characterised by elevated temperature, muscular rigidity, altered consciousness, and autonomic instability) have been reported with abrupt withdrawal of dopaminergic therapy. Therefore, it is recommended to taper treatment (see Section 4.2 Dose and Method of Administration).

Dopamine agonist withdrawal syndrome.

Symptoms suggestive of dopamine agonist withdrawal syndrome (for example, apathy, anxiety, depression, fatigue, sweating, and pain) have been reported with abrupt withdrawal of dopaminergic therapy, therefore, it is recommended to taper treatment (see Section 4.2 Dose and Method of Administration).

Impulse control disorders.

Patients should be regularly monitored for the development of impulse control disorders. Patients and carers should be made aware that behavioural symptoms of impulse control disorders including pathological gambling, increased libido, hypersexuality, compulsive spending or buying, binge eating and compulsive eating can occur in patients treated with dopamine agonists including apomorphine. Dose reduction/tapered discontinuation should be considered if such symptoms develop.
Dopamine Dysregulation Syndrome (DDS) is an addictive disorder resulting in excessive use of Movapo PFS seen in some patients treated with apomorphine. Before initiation of treatment, patients and caregivers should be warned of the potential risk of developing DDS.

Use in debilitated patients.

Extra caution is also recommended in debilitated patients, since they may show an increased susceptibility or be more sensitive to the respiratory depressant effects of apomorphine.

Use in the elderly.

Extra caution is also recommended in geriatric patients, since they may show an increased susceptibility or be more sensitive to the respiratory depressant effects of apomorphine. Extra caution is recommended during initiation of therapy in elderly patients because of the risk of postural hypotension.

Paediatric use.

Movapo PFS is contraindicated for children and adolescents under 18 years of age.

Effects on laboratory tests.

Positive Coombs' tests have been reported for patients receiving apomorphine.

4.5 Interactions with Other Medicines and Other Forms of Interactions

Patients selected for treatment with apomorphine are almost certain to be taking concomitant medications for their Parkinson's disease. In the initial stages of apomorphine therapy the patient should be monitored for unusual side-effects or signs of potentiation of effect.
Drugs which interfere with central amine mechanisms such as tetrabenazine, metoclopramide, antipsychotic dopamine blocking agents (such as phenothiazines, thioxanthenes and butyrophenones), amphetamines and papaverine should be avoided. If their administration is considered essential, extreme care should be taken and the patient monitored for signs of potentiation, antagonism or other interactions and for any unusual adverse effects.
Neuroleptic medicinal products may have an antagonistic effect if used with apomorphine. There is a potential interaction between clozapine and apomorphine.
The possible side effects of apomorphine on the plasma concentrations of other medicinal products have not yet been studied. Therefore caution is advised when combining apomorphine with other medicinal products, especially those with a narrow therapeutic range.
Based on reports of profound hypotension and loss of consciousness when apomorphine was administered with ondansetron, the concomitant use of apomorphine with 5HT3 antagonists including antiemetics (for example ondansetron, granisetron, palonosetron) is contraindicated (see Section 4.3 Contraindications).

Antihypertensive and cardiac active medicinal drugs.

Even when co-administered with domperidone, apomorphine may potentiate the antihypertensive effects of antihypertensive and cardiac active medicinal products.
It is recommended to avoid the administration of apomorphine with other drugs known to prolong the QT interval.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

In a fertility study in male rats, fertility was decreased at 2 mg/kg/day SC, one tenth that of the maximum recommended human dose (based on body surface area). Effects on female fertility have not been determined.
(Category B3)
The safety of using apomorphine during pregnancy has not been established in either human or animal studies. Movapo PFS should therefore not be used in pregnant women, or those likely to become pregnant.
It is not known whether apomorphine is excreted in breast milk although problems in humans have not been documented. Nevertheless, because many drugs are excreted in human milk and because of the potential for serious adverse drug reactions due to apomorphine in breastfed infants, a decision should be made either to discontinue breastfeeding or the drug, taking into account the importance of the drug to the mother.

4.7 Effects on Ability to Drive and Use Machines

Apomorphine has varying degrees of impairment which influences the ability to drive and use machines.
Patients being treated with apomorphine and presenting with somnolence and/or sudden sleep episodes must be informed to refrain from driving or engaging in activities (e.g. operating machines) where impaired alertness may put themselves or others at risk of serious injury or death until such recurrent episodes and somnolence have resolved (also see Section 4.4 Special Warnings and Precautions for Use).

4.8 Adverse Effects (Undesirable Effects)

Very common (> 10%).

Most patients experience injection site reactions, particularly with continuous use. These may include subcutaneous nodules, induration (see Section 4.4 Special Warnings and Precautions for Use), erythema, tenderness and panniculitis. Various other local reactions (such as irritation, itching, bruising, fibrosis and pain) may also occur (see Section 4.4 Special Warnings and Precautions for Use). Care should be taken to ensure that areas of ulceration do not become infected.
Hallucinations have been reported.

Common (1-10%).

Gastrointestinal side effects including nausea and vomiting appear to be the most prevalent adverse effects, however tolerance to these effects develops rapidly. Pre-treatment with domperidone may reduce or prevent these effects (see Section 4.2 Dose and Method of Administration).
Apomorphine is associated with somnolence. Drowsiness and sedation occur in most patients on initial treatment but these effects largely subside with repeated dosing, although in some patients these effects may persist. Tachyphylaxis to postural related faintness or syncope also occurs rapidly.
Neuropsychiatric disturbances (including confusion and visual hallucinations) have occurred during apomorphine therapy.
Yawning has been reported during apomorphine therapy.

Uncommon (0.1-1%).

Apomorphine may induce dyskinesias during 'on' periods, which can be severe in some cases, and in a few patients may result in cessation of therapy. Apomorphine has been associated with sudden sleep onset episodes (see Section 4.4 Special Warnings and Precautions for Use).
Postural hypotension is seen infrequently and is usually transient (see Section 4.4 Special Warnings and Precautions for Use).
Breathing difficulties have been reported.
Local and generalised rashes have been reported. Injection site necrosis and ulceration have been reported.
Haemolytic anaemia and thrombocytopenia have been reported in patients treated with apomorphine.

Rare (0.01-0.1%).

Eosinophilia has rarely occurred during treatment with apomorphine.
Due to the presence of sodium metabisulfite, allergic reactions (including anaphylaxis and bronchospasm) may occur.

Not known (can not be estimated from available data).

Impulse control disorders including pathological gambling, increased libido, hypersexuality, compulsive spending or buying, binge eating and compulsive eating can occur in patients treated with dopamine agonists including apomorphine (see Section 4.4 Special Warnings and Precautions for Use).
Aggression and agitation have also been reported.
Headache has been reported.
Peripheral oedema has been reported.
Dopamine agonist withdrawal syndrome (apathy, anxiety, depression, fatigue, sweating and pain), see Section 4.4 Special Warnings and Precautions for Use.
Neuroleptic malignant syndrome, see Section 4.4 Special Warnings and Precautions for Use.
Other adverse reactions to apomorphine that have been reported infrequently include transient rises in serum prolactin, stomatitis, transient metallic taste, rhinorrhoea, increased lacrimation, reduced facial hair growth, loss of libido and spontaneous penile erection.
Thrombus formation and pulmonary embolism have occurred with central venous infusion of apomorphine. Intravenous infusion of the preparation is thus contraindicated.

Reporting suspected adverse effects.

Reporting suspected adverse reactions after registration of the medicinal product is important. It allows continued monitoring of the benefit-risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions at www.tga.gov.au/reporting-problems.

4.9 Overdose

Symptoms.

The clinical features of overdose of Movapo PFS are an extension of the pharmacological effects of the drug. They include nausea and persistent vomiting, dyskinesias, hypotension and acute circulatory failure, cardiac arrest, respiratory depression, drowsiness and central nervous system depression or stimulation, euphoria, restlessness and hallucinations and possibly coma and death. Concomitant use of domperidone may exacerbate the clinical features of overdose.

Treatment.

An opioid antagonist such as naloxone may be given to treat excessive vomiting, central nervous system depression and respiratory depression due to Movapo PFS overdose. Excessive vomiting may also be treated with domperidone. Atropine may be also used to treat bradycardia. To treat hypotension, appropriate measures should be taken e.g. raising the foot of the bed.

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

Apomorphine is a directly acting dopamine receptor agonist, structurally related to dopamine. Apomorphine has high in vitro binding affinity for the dopamine D4 and D5 receptor (Ki: 4 and 14 nanoM respectively), moderate affinity (Ki: 26 to 130 nanoM) for the dopamine D2 and D3, adrenergic α1D, α2B, α2C receptors, serotonin 5HT1A, 5HT2A, 5HT2B, and 5HT2C receptors and low affinity for the dopamine D1 receptor (Ki: 370 nanoM). Apomorphine exhibits no affinity for the adrenergic β1 and β2 or histamine H1 receptors.
The effect of apomorphine as an antiparkinsonian agent is believed to be the result of direct stimulation of postsynaptic D2 dopamine receptors, but stimulation of presynaptic D2 dopamine receptors and antagonism of α2 adrenergic receptors may also be important. Apomorphine reduces the tremor, rigidity and bradykinesia in patients receiving levodopa. Apomorphine induces vomiting by direct stimulation of the medullary chemoreceptor trigger zone.

Clinical trials.

No data available.

5.2 Pharmacokinetic Properties

The peripheral pharmacokinetics of apomorphine have been studied following subcutaneous injection, subcutaneous infusion and intravenous infusion.

Absorption.

Following intramuscular or subcutaneous administration, apomorphine is reported to be well absorbed. Peak plasma concentration occurs as early as three minutes following subcutaneous bolus injection. The rapid and complete absorption from subcutaneous tissues and rapid clearance is believed to correlate with the rapid onset and brief duration of action respectively. Antiparkinsonian effects are observed within five minutes following subcutaneous bolus administration.

Distribution.

The distribution half life of apomorphine was found to be five minutes. The volume of distribution, plasma clearance and half life were similar for subcutaneous injection, subcutaneous infusion and intravenous infusion.
Apomorphine reaches a concentration in the brain up to eight times higher than that in plasma, due to high lipid solubility which allows rapid equilibration between blood and tissue compartments.

Metabolism.

Apomorphine is metabolised in the liver. Routes of metabolism in humans include sulfation, N-demethylation, glucuronidation and oxidation to norapomorphine by CYP2B6, CYP2C8 and CYP3A4. The major metabolite in humans after sublingual administration was apomorphine sulfate.

Excretion.

Apomorphine is cleared rapidly. The elimination half-life (t1/2) is about 33 minutes.

5.3 Preclinical Safety Data

Genotoxicity.

In vitro genotoxicity studies demonstrated mutagenic and clastogenic effects, most likely due to products formed by oxidation of apomorphine. Apomorphine was not genotoxic in vivo in a mouse micronucleus test or in a rat unscheduled DNA synthesis test.

Carcinogenicity.

No carcinogenicity studies have been performed.
